Can we combat against deepfakes?
I think this game will go pretty crazy, because, at some point, the generator AI will be able to generate absolutely perfect images. Actually, no, just perfect enough that no AI can be sure whether they are real or fake.

So, I think the AI war will go onto more than the image, the detector AI will probably evolve to analyze whether this video is logically plausible, for example, by tracking the celebrities' position to prove that it is impossible that he/she was, for example, let's put it this way, being unloyal to his/her partner.

I mean, currently, AI can tell whether an image is fake or not better than human because it has seen about a million times more samples than us, but if we know who the person in the image is and we are as stalky as the AI I just described, we can probably work out that this image is implausible.

Of course, there will be counter measurements to that. But, at that point, we might as well just let the AI rule the world, given that it will have become this smart (lol).

But, seriously, if it's smart enough to think this far ahead in this 'real world' problem, then strong AI is nigh.
